HUG-LUBRICATING APPARATUS.

Application led May 7,

To all whom t may concern Be it lrnown that we, ALBERT D. FEY, CHARLES S. NICHOLSON, and NED J. NICHOL- son, citizens of the United States, residing at Scranton, in the county of Greene and .State of Iowa, have invented certain new and useful improvements in Hog-Lubricating Apparatus, of which the following is a specification.

The present invention relates to an apparatus for lubricating the skin of animals such as hogs.

One object of the invention is to provide an apparatus of this class consisting of a receptacle firmly erected on the ground and filled with preferably solid grease such as mica axle grease7 and the grease in the receptacle is intended to be compressed from time to time by a piston operated from the outside. The receptacle has perforations communicating with a space formed between the receptacle and a screen stretched over the same and against this screen the hogs will rub their hide to soften the same. This is a much more practical and economical way of lubricating the hides of hogs than the usual method of having a grease-post smeared with fat.

in the accompanying drawing, one embodiment of the invention is illustrated, and

Figure 1 is a partial elevation and partial vertical section of the apparatus, and

Figure 2 is a horizontal section along line 2-2 of Figure 1.

The apparatus consists of a substantially cylindrical container or receptacle 10 having a wide base or foot 11 at its lower end which is adapted to be erected upon a platform'or floor 12 and firmly secured to the same by means of bolts 13 or the like. The container has a straight smooth bore 14 eX- tending from end to end and the lower end of the bore is closed by means of a plate 15 inserted between the floor 12 and the foot 11.

In this bore a piston 16 is slidably mounted and preferably provided with leather or other suitable packing 17 in order to make a close fit in the bore 14. At the upper end of the container a reinforcement or collar 18 is provided and adapted to be closed by means of a dome-shaped cap 19 fitting closely over the same and secured thereto by means of hinge lugs 20 and pins 21. The piston has a threaded stem 22 revolubly mounted therein 1924. Serial No. 711,687.

for engagement with a correspondingly threaded aperture 23 arranged centrally in the dome-shaped cap 19. This stem has sufficient length to permit the piston 16 to reach the top row of apertures 34. At the outer end of the stem or feed screw 22 is provided a hand wheel 24- for turning the stem. By means of the hand wheel the piston 16 may be advanced or retracted in the bore 14 of the container. in order to permit easy assembling of the piston in the bore 14, the latter is slightly enlarged, as at 25, at its upper end.

Extending upwardly from the foot 11 is a reinforcement 27 which surrounds the container, and forms a shoulder 28 at its upper end. About mid-way between the shoulder 28 and the collar 1S is another annular shoulder 29 which also surrounds the container, and is of substantially the same diameter as the reinforcement 27. Around these two shoulders is stretched a preferably fabric cover S0 and over the same is provided a mesh screen 3l. Both the fabric cover and the screen are firmly secured by means of clamping bands 32 at the shoulders 28 and 29. It will be evident that in this manner an annular space 33 is formed around the casing extending from the lower shoulder 28 to the upper shoulder 29 and between these shoulders the cylindrical wall of the container 10 is provided with series of small apertures 34 opening into the space 33.

After the container has been erected on the floor or base 12 as previously described and the cap 19 removed, together with. the piston 16, the chamber 14 is filled with preferably solid grease. With the feed screw turned up all the way so that the piston is substantially level with the lower edge of the cap, the latter is placed on top of the collar 1S and the pins 21 inserted in the hinge lugs 2O so as to close the container at this end. The hand wheel 24 is thereupon turned so as to lower the piston 16 in the chamber 14, thereby compressing the grease therein. The latter will soon commence to ooZe out of the apertures 34 into the space B3 and as soon as this space has been filled, turning of the handle 24 is stopped. The fabric 30 and the screen 31 surrounding the same will now be thoroughly greased and the grease transmitted to the hide of a hog rubbing himself against the screen.

Having thus described the invention, what is claimed as new is:

l. In a lubricating apparatus for animals, a container for lubricating material, a screen around the container and suitably spaced therefrom, the wall of the container being provided with perforations opening into said space, and means for forcing said lubricating material through said perforations into said space. v

2. In-a lubricating apparatus for animals, a container for lubricating material, a screen around the container and suitably spaced therefrom, the wall of the container being provided with perforations opening into said space, and means for forcing said lubrieating material through said perforations into said space; saidscreen including wire mesh secured on said container.

3. In a lubricating apparatus for animals, a container for lubricating material, a screen around the containery and suitably spaced therefrom, the wall of the container being provided with perforations opening into said space, and means for forcing said lubricating material through said perforations into said space; said screen including wire mesh secured on said container, and a fabric lining on the inside of said mesh.

4. In a lubricating apparatus for animals, a container for lubricating material, annular shoulder projecting outwardly from said container and spaced a. suitable distance apart, a screen extending between said shoulders forming a space around the container, perforations provided in the wall of the container between said shoulders opening into said space, and means for forcing thev lubricating material through said perforations into said space.

5. In a lubricating apparatus for animals, a container for lubricating material, annular shoulders projecting outwardly from said container and spaced a suitable distance apart, a screen extending between said shoulders forming a space around the container, perforations provided in the wall of the container between said shoulders opening into said space, and means for forcing the lubricating material through said perforations into said space; said screen including wire mesh, and a fabric lining on the inside of said mesh.

6. In a lubricating apparatus for animals,

a container for lubricating material, annular shoulders projecting outwardly from said container and spaced a suitable distance apart, a screen extending between said shoulders forming a space around the container, perforations provided in the wall of the container between said shoulders opening into said space, and means for forcing the lubricating material through said perforations into said space; said screen including wire mesh, a fabric llining on the inside of said mesh, and clamps securing said screen upon said shoulders.

7. In a lubricating apparatus for animals, a container for lubricating material, aImular shoulders projecting outwardly from said container and spaced a suitable distance apart, a screen extending between said shoulders forming a space around the con tainer, perforations provided in the wall of the container between said shoulders opening into said space, and means for forcing the lubricating material through said perforations into said space; said screen including wire mesh, a fabric lining on the inside of said mesh, and clamps securing said screen upon said shoulders; said means including a piston slidably mounted in said container, a feed screw secured to said piston, a cap closing the end of the container having threaded engagement with said feed screw, and a hand wheel on the.v feed screw.
